Description

sinking fish egg incubator

technical field

The invention relates to a super-intensive aquaculture equipment, in particular to a sinking fish egg incubator.

Background technique

During the hatching process of fertilized fish eggs, sinking fish eggs accumulate at the bottom of the water due to their large specific gravity, and they are squeezed against each other, which is very easy to cause damage. Low, high deformity rate of larvae and other problems. The existing hatching methods use hatching boxes or hatching tanks, etc., only relying on methods such as increasing the number of aeration stones and reducing the hatching density can not really solve the problem of fish egg accumulation. On the other hand, the hatching equipment and facilities are large in size and occupy a large area , high water consumption, complex operation, high difficulty, and low hatching efficiency greatly restrict the success rate of sinking fish eggs hatching. The commonly used incubator/cabinet in recent years adopts the method of reducing the hatching density of fish eggs, which alleviates the problem of insufficient dissolved oxygen of fish eggs to a certain extent, but it is bulky, occupies a large area, is difficult to operate, and is expensive. Meet the needs of ordinary nursery farms. Existing technologies such as the Chinese utility model patent "A Submerged Fish Egg Upwelling Automatic Incubator", patent number 201220711934.2, this utility model discloses a sinking fish egg upwelling automatic incubator, which can solve the problem of sinking fish eggs in the prior art. Sexual fish eggs sink to the bottom of the water during the hatching process and cannot obtain sufficient dissolved oxygen due to accumulation, making hatching difficult. The technical solution of this utility model is an automatic upward-flowing incubator for sinking fish eggs, which includes a base, an incubation container, a control valve, a water inlet pipe and a water pump. The base is connected, the outlet of the water pump is connected with the water inlet pipe, the control valve is arranged on the water inlet pipe, a plurality of balls are arranged on the inner bottom of the base, and a filter screen is arranged on the balls .
